看到「Amazon EFS now supports a larger number of concurrent file locks」這篇提到：
This Amazon EFS update increases the number of simultaneous file locks an NFS mount can acquire to 65,536 (from 8,192 previously), enabling Amazon EFS to be used for a broader set of applications that heavily leverage file locking (including message broker and distributed analytics applications).
所以 NFS 的部份先前有 8192 個的上限在，現在則是拉 65536 個了。
不過提到 message broker，應該是以前的應用利用 NFS file lock 來做一些事情？
